The fashion house is amping up its legal battle against the fast fashion company

The legal battle between Gucci and Forever 21 isn’t dying down anytime soon.

Back in December, the Italian fashion house sent the fast fashion retailer the first of several cease-and-desist letters demanding the discontinuation of all items featuring Gucci’s trademark “blue-red-blue” and “green-red-green” stripes. At the time, Forever 21 had several pieces — ranging from bomber jackets to chokers and sweaters — that looked extremely similar in design to Gucci’s striped items.

Continuing the legal battle this week, Gucci amped up its fight against the fast fashion retailer with two counterclaim suits filed within the U.S. District Court, Central District of California. According to Fashionista, the counterclaims filed were for trademark infringement, trademark dilution, unfair competition, and the dismissal of the retailer’s earlier claims.

“Gucci has today taken steps to finally put an end to U.S. mass retailer Forever 21’s blatant exploitation of Gucci’s famous and iconic blue-red-blue and green-red-green stripe webbing trademarks,” Gucci said in a statement released to Fashionista today.

The brand continued, “Despite Forever 21’s attempt to use its lawsuit to intimidate Gucci into ceasing its trademark enforcement efforts, Gucci is as committed as ever to protecting its long established intellectual property rights.”

Forever 21 has yet to publicly respond to the lawsuit, but it’s unlikely that this is over just yet.
